Terne II
Classic T erne-Coated Steel

Terne II is a new and improved version of historic
Terne metal, which was used extensively throughout
both colonial and modernistic America. While it
retains all the time-tested qualities of the original,
Terne II has improved capability for resisting
corrosion in all environments. Terne II also has
excellent formability, solderability, and affinity for

paint.
Specifications
Terne II offers its enhanced corrosion-resisting
Warranty capability without compromising mechanical
characteristics. It can be used in flatlock, standing
Installation
seam, vertical wall designs and virtually any other
Rapidri Coatings application in which original Terne has been used. It
is strong and ductile, having high yield and tensile
Accessories
strengths as well as workability. This new material
can easily be formed with conventional roofing

tools.
With Terne II roofing, it is advisable to paint the
material as soon as conditions permit. Oxide
formation is slower than with the original Terne and
the wait for proper painting conditions provides
substantially less risk. The new material is coated
with Follansbee's new ZT® alloy, a combination of
zinc and tin. This coating is designed not only as a
barrier but also to be anodic to the steel substrate and
reduce the potential for oxidation before painting.
The traditional oil-based paints long required on
original Terne are not recommended for application
on Terne II. Follansbee's Rapidri paint with its faster
drying time and ease of application is much superior
to the old painting system. The Rapidri acrylic paints
are aesthetically pleasing while offering enhanced
durability and color retention. Speedier contractor
turnaround is accomplished since the state of the art
acrylic/ceramic enamel paint can be spray applied.
Because Terne II is easily soldered, it provides
weather-tight joints around roof perimeters and
penetrations. As a result, roofers do not have to rely
on sealants, which have a limited life and require
maintenance and are assured that these areas of
possible water penetration will remain watertight.
For soldering, only pure tin solder is recommended.
Terne II is an excellent material for restoration
projects since it replicates many of the older roofs of
Terne which have served through many decades.
Terne II Residential Grade (RG)

The RG grade of Terne II is engineered and targeted
at the largest segment of the Terne II market - the
residential customer. Follansbee's experience,
combined performance testing, has given birth to an
economical version of Terne II, which will
outperform all other commonly available metals
used for residential application. The RG series of
Terne II offers the homeowner the beauty, history
and endurance of metal residential roofing at an
affordable price.

Terne II Commercial Grade (CG)

The CG grade of Terne II is engineered for
application on commercial, institutional or
governmental structures. CG offer the maximum ZT
alloy coating thickness available. Formability,
solderability and enhanced corrosion resistance are
inherent in the CG grade of Terne II. CG accepts
paint readily and should provide the owner with
many years of service.
